Be it known that I, CHARLES ILLInuS, of Manchester, in the county ofIIillsboro, and State of New Hampshire, have invented an ImprovedCooking-Stove; and do hereby declare the same to befully described inthe following specification, and represented in the accompanyingdrawings, of which Figure 1 is a vertical and longitudinal section ofit.

Figure 2 is a top view.

Figure is a horizontal section taken through the smoke-flue over theupper oven.

.Figure 4 is a horizontal section taken through the. smoke-dues betweenthe two ovens.

Figure 5 is a transverse-section taken through the two ovens.

Figure 6 a transverse section taken through the fire-place, theash-drawer and screen, and the chambers thereof. I I

In making the stove I have endeavored to avoid the adoption of the usualash-chamber or pit arranged underneath and opening through the hcarth ofthe stove, the object of such avoidance being to keep the hearth cool,so as to prevent it from burning or scorching the clothes or person of acook when against it, and also to cause the ashes and cinders to fall bytheir own gravity into the ash-Sifter and the ash-drawer. I thus savethe employment of a chute or inclined plane for conveying the ashes fromthe grate to the sifter, and as a coin sequence render unnecessary anyraking forward of such ashes on such plane, as frequently becomesrequisite when such plane is used. I have also constructed the mainovenin part of stcatite slabs or panels, and metallic frames for holdingthem in place. I have also a new arrangement of dues about the ovens.

In the drawings, A denotes the fire-place; B the upperand C the lower oftwo ovens, one of which'is arranged directly in rear of the fire-placeand against the back plate a thereof, such back plate serving to formone side of the oven., The lower oven C is arranged against or on alevel with the ash-sitter and drawer chambers D E, one of which isdisposed directly over the other, and both are placed wholly underneaththe fire-place whose grate, F, is supported so as to be capable of beingrevolved in order to discharge ashes and cinders from it directly intothe ash-siftor G. The said ash-sitter is arranged so as to restonledges, b I), which are on or about on a level with the hearth U, whichis a sheifprojccting from the front of the stove and between the ashsifter and its drawer H, or the chambers D E of the two. There is nodepression or ash-chamber in the hearth, but-the air is free tocirculate wholly underneath the hearth, so as to keep it cool. Thedrawer H is to be inserted into the chamber E, and to be withdrawntherefrom through an opening, 0, in its front and from under neath thehearth. The ash-sifter, which is a rectangular box, open at top, andprovided with a grate, a, in its bottom, is to be withdrawn from itschamber or introduced into it through an opening, d, in the front plateof the stove. A rod, 2, extending through a hole,f, in one side of thestove, and provided with a catehph, as

shown in fig. 7, by having such catch inserted in a rectangular orelongated opening made in one end of the sifter, and being turned ninetydegrees thereon, becomes so connected Withthe siftcr as to enable aperson by means of such rod to move the sifter longitudinally andquickly back and forth, so as to sift from it any ashes, which will fallinto the ash receptacle. After having disengaged the rod c from thesifter, the latter may be withdrawn from its chamber in order for thedischarge into the fire-place of the coals or cinders left in thesifter. A flue, I, extends entirely over the upper oven and underneaththe top plate 9 of the stove. Leading downward from the flue I, and inrear of the upper oven, are three descending fines, KL M. The middle oneof these fines extends up to and opens through the top plate of thestove, and is provided with a damper, 79, where it opens out of the flueI, such damper bein'g fixed to a rod or shaft, Zi",--' leading throughone side of the stove. The said flue L is closed at its bottom, butopens out of the middle flue O", of the three flues N O P, arrangedbetween the two ovens, and communicating together by openingsz'z', asshown in fig. 4.. The two flues K M open at their lower ends into avertical fluespace, R, which extends entirely across the back of thelower oven. Furthermore, there are openings, k 70, leading from thefines K M into the fines N P, such openings being provided with dampersZZ, attached to a rod, 12:, going through one side of the stove. At thelower part of the flue L there is an opening, 11 made through the rearend plate of the stove, and on a level with the fine 0, such opening,when the stove is in use, being provided with a door or cover. Thisopening is to facilitate the clearing of the flue OJ ll'urthermore,there is a fine, S, extending underneath the'bottom of the lower ovenand opening out of the flue-space R, and into a flue, T, which goes upagainst the front end of, the lower oven and between it andtheash-sifter and box chambers D E. The flue T, at its upper end, opensinto the dues between the two ovens. The bottom, the top, and eachvertical end of the oven, I construct of a rectangular frame, 0 and apanel, 19, of soapstone or' steatite fixed in the opening of such frame.In this way I construct an oven more retentive of heat than it would beif made entirely of iron or metal, The iron bottom plate of the stoveshown at r extends entirely beneath the oven and the fire-placeunderneath the lower oven. I would observe that the dampers Z I, whenturned into horizontal positions or thereabouts, interrupt communicationbetween the tines K M and the flue R, and thereby cause the smoke afterits passage down the said fiues K M to How into the two fines N P. Byopening the upper damper h the smoke from the flue I will escape throughthe opening of the top plate of the stove instead of passing into thetines K M. By the above-mentioned peculiar arrangement of fines anddampers the smoke and volatile products of combustion issuing from thefire-place, when the latter is charged with fuel in a state of ignition,may be caused to circulate about both ovens, or only around the upperone of them, as circumstances may require. So, for instance, if we raisethe lower dampers into vertical positions, the smoke will pass fromtheflucs'K M into the flue R, from thence into and through the flue S,thence into and up the flue T, thence into the flue-space or spacesbetween the two ovens, and thence into and up the flue L. By turningdown the lower dampers, the smoke will pass directly from thediving-fines K M into the flues N P, thence-into the flue O, and thenceinto and up the flue L, heating in its coursethe top, back, and bottomof the upper oven, and the top only of the lower one. o

I make no claim to an oven made of soapstone or stcatitc; nor do I claiman even made with an iron case and a soapstone lining contained thereinnor do I claim a stove made with soapstone sides and a fire-pot arrangedwithin it, and so that the space between the pot and the soapstone maybe used as an even. I have arranged the flue-space outside of the ovenand against soapstone panels and metallic frames to hold them, andbetween such and the outer metallic case of the stove. I make no claimto the arrangement of flues, and ovens, and dampers as represented inLetters Patent No 3,861, dated December 19, 18-14, and in Letters PatentNo. 77, additional thereto, and dated July 5, 1845. --I combine, withsuch an arrangement of ovens and fines as is shown in such additionalpatent, a flue opening and damper h thereto, whereby the heat and smoke,instead ofbeing made to circulate through the diving-fines and abouteither or both the ovens, may be led directly from the flue I over theupper even into the chimney or escape-flue, therebysaving at timesunnecessary heating of either or both the ovens.

What I claim as of my invention in such stove is as follows:

I claim the arrangement of the hearth U, the ash-sitter G, and box H,their chambers D E, and the fireplace A.

I also claim the combination and arrangement of the two ovens B C, theashsiftcr and box chambers D E,

the fire-place A, the fines I K L M N O P R S and T, and dampers I71, II, as set forth. I
